The Problem

• People searching for Music and not finding

Piano teachers

Solution

• NCO

• Normalised Co-Occurrence

• Inference to semantic distance

• Actually co-interest

• Useful community-specific data

the community’s interests change

• Like pulling a hierarchical vocabulary out of a

freetagging vocabulary: magic
